Description

Technical Field

[0001] The present invention relates to the technical field, and particularly to a swinging structure and a corresponding water outlet device. Background Art

[0002] Some existing water outlet devices have a water outlet function of forming swinging water flowers. Generally, to achieve this water outlet function, a swinging structure needs to be provided inside the water outlet device. This swinging structure then drives the water outlet member to swing relative to the water outlet device body, so that the water flowers have a swinging effect. Generally speaking, at present, the impeller is more commonly used as the main driving component in the swinging structure. After the water flow impacts the impeller, it will drive the impeller to rotate. The impeller then cooperates with multiple sets of gears, so that the final water outlet member can swing back and forth within a certain angle range. Since the impeller rotates at a high speed, multiple sets of gears are needed to make the swinging frequency of the swinging water flowers within an appropriate range. Therefore, its overall structure is relatively complex, the reliability is low, and the manufacturing cost is also high. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned defects or problems existing in the background art, and provide a swinging structure and a corresponding water outlet device. This swinging structure can be used in a variety of different scenarios. By directly impacting the swinging member with water flow, the swinging member is made to perform reciprocating swinging motion, and then it cooperates with the water outlet member or stirs the water flow at the water outlet, thereby forming swinging water flowers. The overall structure is relatively simple, the reliability is higher than that of the existing water outlet devices with swinging water outlet function, and the manufacturing cost is also reduced.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A swinging structure, comprising: a body, which is provided with a water passing cavity, an inlet hole and an outlet hole that are respectively communicated with the water passing cavity and are located on the upper and lower sides of the water passing cavity; a swinging member, which is swingably connected to the body around a swinging axis and is located in the water passing cavity. The two side walls perpendicular to the swinging axis of the swinging member are in clearance fit with the corresponding two side cavity walls of the water passing cavity, and the swinging member is provided with a first end portion and a second end portion that are respectively located on the upper and lower sides of the swinging member relative to the swinging axis; the first end portion is provided with a groove whose opening faces the inlet hole when the swinging member is in the initial position only under the action of gravity; the swinging member is configured to be suitable for receiving the impact of the water flow guided by the inlet hole, and its first end portion and second end portion are close to or abut against the cavity wall of the water passing cavity after the second end portion crosses the range of the outlet hole.

[0006] Furthermore, the water passing cavity is enclosed by a first cavity wall and a second cavity wall, and a third cavity wall and a fourth cavity wall which are opposite to each other in position; the first cavity wall and the second cavity wall are in clearance fit with the swinging member; a part of the third cavity wall and the fourth cavity wall adjacent to the water inlet hole are away from each other along the water inlet direction, and a part of them adjacent to the water outlet hole are close to each other along the water outlet direction.

[0007] Furthermore, when the swinging member swings to the maximum angle position, the opening of the groove is located on one side of a plane parallel to the water inlet direction of the water inlet hole and passing through the swinging axis.

[0008] Furthermore, the force arm from the first end of the swinging member to the swinging axis generated by the action of water flow is smaller than the force arm from the second end of the swinging member to the swinging axis.

[0009] Furthermore, the hole walls of the water inlet hole are close to each other along the water inlet direction.

[0010] Furthermore, a water inlet swinging member is also installed upstream of the water inlet hole; the water inlet swinging member is provided with a swinging member water inlet, a U-shaped wall with an opening facing the swinging member water inlet, two fluid channels located at both ends of the U-shaped wall, and a cross water outlet communicating with the two fluid channels at the same time; the cross water outlet is communicated with the water inlet hole.

[0011] Furthermore, a water inlet swinging member is also installed upstream of the water inlet hole; the first base body is provided with a water inlet cavity communicated with an external water pipe; the bottom of the water inlet cavity is communicated with the water inlet hole; the water inlet swinging member is rotatably connected to the water inlet cavity, and is provided with a swinging member thereon; the swinging member is configured to be suitable for swinging under the impact of water flow and disturbing the water flow entering the water inlet hole.

[0012] In addition, the present invention also provides the following technical solutions:

[0013] A water outlet device adopts a swinging structure as described in any one of the above; the hole walls of the water outlet hole are away from each other along the water outlet direction.

[0014] Furthermore, the body includes a first base body and a second base body which are fixedly connected to each other, and the two cooperate to form the water passing cavity; the swinging member is rotatably connected to the first base body or the second base body.

[0015] Furthermore, the second base body is fixedly connected to a plurality of the first base bodies, and correspondingly forms the water passing cavities with the same number as the first base bodies, and a swinging member is installed in each water passing cavity.

[0016] In addition, the present invention also provides the following technical solutions:

[0017] A water outlet device adopts a swinging structure described in any one of the above; it further includes a water outlet member; the water outlet member is rotatably connected to the swinging member and is provided with a water outlet located outside the body and communicating with the water outlet hole of the water passing cavity; the axis of the water outlet intersects the projection of the swinging axis on at least one plane.

[0018] Furthermore, the body is provided with a water passing channel; the water outlet member is provided with a water outlet channel communicating with the water outlet; the bottom of the water passing channel communicates with the water passing cavity through the water outlet hole, and its top communicates with the water outlet channel.

[0019] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. A water passing cavity is arranged in the body, and a water inlet hole and a water outlet hole are arranged on the upper and lower sides of the water passing cavity. Water flow can enter the water passing cavity through the water inlet hole and be discharged from the water outlet hole. At the same time, a swinging member swingably connected to the body is arranged in the water passing cavity. A groove is provided at the first end of the swinging member located at the upper side position. When the swinging member is only affected by gravity, the swinging member will be in an initial balanced position relative to the body. At this time, the opening of the groove on its first end will point to the water inlet hole, which causes the water flow to impact into the groove after entering the water passing cavity. Due to the impact of the water flow and the uneven force on the bottom wall and side wall of the groove due to the shape, a torque will be generated on the swinging member. Initially, the direction of this torque is random, which will cause the swinging member to swing randomly towards one side. When the second end of the swinging member located at the lower side crosses the range of the water outlet hole, the first end and the second end of the swinging member will be close to or abut against the cavity wall of the water passing cavity. Since the swinging member itself has a clearance fit with the water passing cavity in the direction perpendicular to the swinging axis, when both the first and second ends of the swinging member are close to or abut against the cavity wall, it will cause the water passing area between the water inlet hole and the water outlet hole in the water passing cavity to decrease. At this time, the swinging member will divide the water passing cavity into a chamber that only communicates smoothly with the water outlet hole and a chamber that only communicates smoothly with the water inlet hole. As the chamber communicating with the water outlet hole is depressurized, the torque received by the swinging member changes, prompting the swinging member to swing back to the initial position and, due to inertia, cross the initial position. At this time, the water flow will impact the first end of the swinging member again, thereby prompting the swinging member to have sufficient torque to continue swinging, and further causing the swinging member to form a reciprocating swing under the action of the water flow through the above process; through the structural cooperation between the swinging member and the water passing cavity, the swinging member can achieve a reciprocating swing under the action of the water flow without designing a complex structure, and the swinging speed of the swinging member can be changed by adjusting the geometric structure of the swinging member itself, reducing the complexity of the swinging structure in the water outlet device, reducing the manufacturing and use costs, and improving the reliability and service life.

[0021] 2. Let the first and second cavity walls of the water passage cavity be in clearance fit with the swing member, which can ensure that most of the water flow can only pass through both sides of the swing member and cannot pass between the swing member and the first and second cavity walls of the water passage cavity. At the same time, maintaining the clearance fit enables the swing member to swing smoothly. Let the third and fourth cavity walls of the water passage cavity move away from and close to each other at the positions of the water inlet hole and the water outlet hole respectively, forming an inclined wall structure, which can make the first end and the second end of the swing member close to or abut against the third and fourth cavity walls after swinging in place, and can ensure that there is enough water flow from the water inlet hole to the water outlet hole when the swing member is in the initial position or near the initial position.

[0022] 3. Let the opening of the groove be on one side of the plane parallel to the water inlet direction of the water inlet hole and passing through the swing axis when the swing member swings to the maximum angle, so that the water flow impacts on the outer side of the swing member rather than in the groove at this time, thereby reducing the change speed of the torque of the swing member, being beneficial to reducing the swing frequency of the swing member, and can also ensure that the swing member has a larger swing amplitude and avoid the swing member not swinging in place.

[0023] 4. The swing member has a fulcrum at its swing axis position. The action of the water flow on the swing member will cause corresponding torques at the first and second ends of the swing member. The magnitude of the torque is related to the magnitude of the force arm. Setting the position of the fulcrum of the swing member to be closer to its first end can make the magnitudes of the force arms from the first and second ends to the swing axis form a difference. When the swing member swings to the maximum angle position, due to the different torques at the first and second ends, it will cause the swing member to return to the initial position.

[0024] 5. Let the hole walls of the water inlet hole approach each other along the water inlet direction, which can effectively increase the water inlet flow rate and the impact force of the water inlet on the swing member, and prompt the swing member to swing randomly towards one side at the initial stage.

[0025] 6. An inlet swing member is arranged upstream of the water inlet hole. The inlet swing member can make the water flow impact on the U-shaped wall and alternately pass through the two fluid channels at both ends, and finally flow out from the cross-shaped water outlet, so that the water flow forms a swinging water outlet state at the cross-shaped water outlet. Such water flow will better prompt the swing member to swing after impacting on the swing member.

[0026] 7. An inlet swing member is arranged upstream of the water inlet hole. When the water flow impacts the inlet swing member, it will cause the inlet swing member to rotate, thereby disturbing the water flow and making the water flow impact the swing member in a more disordered state, so as to better prompt the swing member to swing.

[0027] 8. Provide a water outlet device. The hole walls of the water outlet holes on the body of the water outlet device are spaced apart from each other along the water outlet direction. This enables the water in the water passing cavity to shoot out from the water outlet holes along the inclined direction of the swing member after the swing member passes over the position of the water outlet holes, and the hole walls of the water outlet holes do not restrict the water outlet direction. This allows the swing member to directly form reciprocating swing water flowers through swinging. The overall structure of the water outlet device is extremely simple, and the effect of the formed swing water flowers is good.

[0028] 9. In the water outlet device, the body is composed of a first base body and a second base body. The two are fixedly connected to each other and cooperate to form a water passing cavity. The split design facilitates the installation of the swing member, and the swing member can be installed on one of them through a rotating shaft or the like.

[0029] 10. There is one second base body, and multiple first base bodies can be provided. After the second base body is fixedly connected to the first base body, multiple water passing cavities can be formed. A swing member is installed in each water passing cavity. Through such a structure, swing water flowers can be formed at multiple positions of a water outlet device, which is suitable for applications in scenarios such as shower heads.

[0030] 11. Provide a water outlet device. The water outlet device further includes a water outlet member. The water outlet member is provided with a water outlet that is exposed outside the body and communicates with the water passing cavity. The water outlet member is synchronously swung with the swing member through anti-rotation cooperation with the swing member, and the water outlet also forms swing water flowers accordingly. The overall structure is simple, and the effect of the formed swing water flowers is good.

[0031] 12. A water passing channel is provided in the body of the water outlet device. The bottom of the water passing channel is connected to the water outlet holes at the bottom of the water passing cavity to introduce water into the channel of the water outlet member. The water outlet member can be directly in anti-rotation cooperation with the swing member coaxially, thereby reducing the complexity of the setting of the water outlet member and also reducing the complexity of the overall structure of the water outlet device.

[0060] Embodiment 1

[0061] See Figure 1 , Figure 1 shows an exploded view of a water outlet device provided by Embodiment 1 of the present invention. The water outlet device mainly includes a body, a first sealing ring 17, a swing member 20 and a water outlet assembly.

[0062] The body includes a first base 10 and a second base 16.

[0063] Refer to Figure 2 and Figure 3 , the first base 10 is a cylindrical member, and a through structure penetrating its upper and lower ends along its axial direction is provided inside it, so as to Figure 3Taking the view of

[0064] as an example, the cross-section of the through structure in the direction perpendicular to the axial direction of the first base body 10 is rectangular, and openings are provided at both its upper and lower ends. The opening at its upper end forms a water inlet hole 112, and the hole wall of the water inlet hole 112 gradually narrows from top to bottom, which is convenient for increasing the flow velocity of the water flow ejected from the water inlet hole 112; an opening is also formed at the lower end of the through structure, and the size of this opening is relatively large. An inlet joint 11 is provided on the upper surface of the first base body 10, and threads are provided on the outer side wall surface of the inlet joint 11. Through the external threads, the inlet joint 11 can be connected to an external water inlet pipe. An inlet channel 111 is provided inside the inlet joint 11, and the lower end of the inlet channel 111 communicates with the water inlet hole 112 for introducing water into the water inlet hole 112. Threads are provided on the outer wall at the lower side position of the first base body 10, and these threads are used for screwing connection with the second base body 16. A sealing ring groove is also provided below the threads, and this sealing ring groove is used for installing the first sealing ring 17 to form a seal between the first base body 10 and the second base body 16 to avoid water leakage. Figure 3 Inside the first base body 10, a water separation plate 13 is provided. Referring to

[0065] the above-mentioned chamber is formed on the right side of the water separation plate 13, another chamber is formed on the left side of the water separation plate 13, and the bottom end of the water separation plate 13 is higher than the lower end surface of the first base body 10, which enables these two chambers to communicate through the space below the water separation plate 13. In addition, an insertion hole penetrating the above two chambers is also provided on the water separation plate 13.

[0066] On the first base body 10, an installation hole for installing the water outlet assembly is also provided. The opening of this installation hole is provided on the side wall of the first base body 10, and internal threads are provided on the inner wall of the installation hole near its opening. A blocking wall 18 extending towards the axis of the installation hole is provided on the inner wall of the installation hole near the left chamber of the above-mentioned water separation plate 13. Figure 1 、 Figure 2 and Figure 3 , its shape is adapted to the shape of the threaded area on the lower side of the first base body 10, and internal threads adapted to the first base body 10 are provided on its inner wall, and it can be fixed on the first base body 10 through thread cooperation. At the same time, two symmetrical protruding structures protruding towards the position where the first base body 10 is located are provided inside the second base body 16. These two protruding structures can be inserted into the internal chamber of the first base body 10 from the opening below the first base body 10 after the second base body 16 is fixedly connected to the first base body 10, and cooperate with the first base body 10 to form a water passing chamber 12, and cooperate to form a water outlet hole 15 at the bottom of the water passing chamber 12. At the same time, the second base body 16 closes the opening below the first base body 10, so that a water passing chamber 12 and a water passing channel 14 are respectively formed on both sides of the water separation plate 13, and the water passing chamber 12 and the water passing channel 14 communicate through the water outlet hole 15 at the bottom.

[0067] Further, the water passing cavity 12 can be regarded as being composed of four cavity walls. Referring to Figure 3 and Figure 6 , in Figure 3 , the two side walls on the left and right sides of the water passing cavity 12 are respectively the first cavity wall 121 and the second cavity wall 122. The wall surfaces of the first cavity wall 121 and the second cavity wall 122 are parallel to each other, and the distance between the two is relatively close; in Figure 6 , the two side walls on the left and right sides of the water passing cavity 12 are respectively the third cavity wall 123 and the fourth cavity wall 124. Both the third cavity wall 123 and the fourth cavity wall 124 are formed by the cooperation of the first base body 10 and the second base body 16, and their shapes are symmetrical in the cross-section shown in Figure 6 . At the position adjacent to the opening of the water inlet hole 112 in the water passing cavity 12, the third cavity wall 123 and the fourth cavity wall 124 are far away from each other, and when the third cavity wall 123 and the fourth cavity wall 124 extend to the lower part of the body, the cavity walls at the position adjacent to the opening of the water outlet hole 15 in the water passing cavity 12 formed by the protruding structure on the second base body 16 approach each other along the water outlet direction.

[0068] The swinging member 20 is installed in the water passing cavity 12 and is swingably connected to the body around the swinging axis. Referring to Figure 3 , the width of the swinging member 20 in the view shown in Figure 3 is approximately equal to the distance between the first cavity wall 121 and the second cavity wall 122. This enables the side walls on both sides of the swinging member 20 perpendicular to its swinging axis to respectively form a clearance fit relationship with the first cavity wall 121 and the second cavity wall 122 of the water passing cavity 12. It is difficult for water flow to pass through this gap, and at the same time, it does not affect the swinging of the swinging member 20 in the water passing cavity 12.

[0069] Referring to Figure 4 , the swinging member 20 can be regarded as a lever member, which has two ends. Taking the view in Figure 6 as an example, the upper and lower sides thereof respectively form a first end 23 and a second end 24, and both can be regarded as the concentrated areas where the swinging member 20 is stressed; there is a shaft hole 21 provided between the first end 23 and the second end 24, and this shaft hole 21 is relatively closer to the first end 23, which makes the lengths of the swinging member 20 on both sides of the shaft hole 21 unequal; the swinging axis of the swinging member 20 and the axis of the shaft hole 21 are on the same straight line. There is a groove 22 provided at the position of the first end 23 of the swinging member 20. The opening of the groove 22 faces upward, and it is a through groove with both ends not closed. In addition, two side walls parallel to its swinging axis are formed on the outer side of the swinging member 20, which are respectively the first side wall 25 and the second side wall 26, and these two side walls are the stress surfaces for the swinging member 20 to be affected by water flow in the water passing cavity 12.

[0070] The water outlet assembly includes a water outlet part, a bearing 41, a retaining ring 42, a V-shaped sealing ring 43, a nut 44, a second sealing ring 451, and a third sealing ring 452.

[0071] Among them, the water outlet part includes a water outlet part body 30 and a water outlet joint 46.

[0072] Refer to Figure 5 , the water outlet part body 30 is generally a cylindrical member. According to the direction of the water outlet part body 30 shown in Figure 3 , at the right end of the water outlet part body 30, there is a plug shaft 32 extending axially outward along the water outlet part body 30. This plug shaft 32 can pass through the plug hole on the water isolation plate 13 and insert into the shaft hole 21 on the swing part 20 to form a non-rotating fit, and can drive the water outlet part body 30 to swing when the swing part 20 swings; on the left side of the plug shaft 32, there is a limiting surface 33, which faces the direction pointed by the plug shaft 32 and can abut against the wall surface of the water isolation plate 13 to limit the length of the plug shaft 32 extending into the shaft hole 21. Along the circumferential direction, there is a circumferential abutting flange 31 on the side wall of the water outlet part body 30 near the plug shaft 32. This abutting flange 31 can be in abutting cooperation with the end surface of the blocking wall 18 in the mounting hole on the first base 10 to form a complete blocking wall surface, facilitating the installation of the retaining ring 42, the bearing 41, etc. At the left end of the water outlet part body 30, there is a plug protrusion 34 extending outward along a direction parallel to its axis. This plug protrusion 34 is used for plugging and cooperating with the water outlet joint 46. At the position on the side wall of the water outlet part body 30 near the plug protrusion 34, there are two sealing ring grooves, which are respectively used for installing the second sealing ring 451 and the third sealing ring 452.

[0073] Inside the water outlet part body 30, there is a water outlet channel 36 formed, and at the same time, there is a water inlet 35 communicating with the water outlet channel 36. After the water outlet assembly is installed on the first base 10, the water inlet 35 communicates with the water passing channel 14.

[0074] The water outlet joint 46 is sleeved on one end of the water outlet part body 30 where the plug protrusion 34 is provided, and is in plugging cooperation with the plug protrusion 34, so that it can be fixed on the water outlet part body 30 and achieve sealing through the above-mentioned second sealing ring 451 and third sealing ring 452. There is a water outlet 461 on the water outlet joint 46. The water outlet 461 communicates with the water outlet channel 36 of the water outlet part body 30, and its opening axis is perpendicular to the swing axis of the swing part 20.

[0075] After the water outlet body 30 is inserted into the mounting hole on the first base 10, a bearing 41, a retaining ring 42, a V-shaped sealing ring 43, and a nut 44 are sleeved on the water outlet body 30 in sequence from inside to outside. Through the screw connection between the nut 44 and the internal thread of the mounting hole, the retaining ring 42 can abut against the outer ring of the bearing 41, thereby preventing the bearing 41 from rotating relative to the first base 10; at the same time, the water outlet body 30 can rotate smoothly relative to the first base 10 through the bearing 41; the V-shaped sealing ring 43 can prevent water from leaking out after flowing from the water passage 14 to the mounting hole.

[0076] Refer to Figure 6 、 Figure 7 and Figure 8 , and a detailed description of how the swing member 20 achieves reciprocating swing will be given here.

[0077] When the swing member 20 is only affected by gravity, due to the position of its own center of gravity, it will be in the initial position as shown in Figure 6 . At this time, there is no water accumulation or flow in the water passage cavity 12, the opening of the groove 22 points to the opening of the water inlet hole 112 in the water passage cavity 12, and at the same time, the opening of the water inlet hole 112 in the water passage cavity points to the swing axis of the swing member 20.

[0078] Then the water flows from the water inlet hole 112 into the water passage cavity 12. After the water flows in from the water inlet hole 112, it first impacts into the groove 22. Due to the turbulence formed after the water impacts the groove 22, a force will be exerted on the first end portion 23 of the swing member 20, forming a torque that pushes the swing member 20 to swing, prompting the swing member 20 to swing to the left or to the right. At this time, the swing direction is random. In this embodiment, it is assumed that the first end portion 23 of the swing member 20 first swings to the left.

[0079] Under the impact of the water flow, the swing member 20 starts to swing from the initial position to the first position as shown in Figure 7 . During this process, the first end portion of the swing member 20 is always impacted by the water flow and generates a large enough torque until the swing member 20 swings to the maximum angle position, that is, at the first position. At this time, the opening of the groove 22 of the swing member 20 deviates from the position of the water inlet hole 112. At this time, the opening of the groove 22 is located on the left side of the plane parallel to the water inlet direction of the water inlet hole 112 and passing through the swing axis of the swing member 20, which enables the water flow to impact the second side wall 26 at the first end portion 23 of the swing member 20.

[0080] During the above process of swinging from the initial position to the first position, the second end portion 24 of the swinging member 20 is also in a swinging state. And due to the shape characteristics of the fourth chamber wall 124 on the water passage chamber 12, after the second end portion 24 passes beyond the range of the water outlet hole 15, a water passage gap with a narrow water passage area is formed between the second end portion 24 and the fourth chamber wall 124. During this process, since the moment exerted by the water flow on the first end portion 23 is still greater than the moment exerted by the water flow on the second end portion 24, after the water passage gap is formed between the second end portion 24 of the swinging member 20 and the fourth chamber wall 124, the swinging member 20 will still continue to swing to the first position as shown in Figure 7 At this time, a water passage gap is also formed between the first end portion 23 and the third chamber wall 123. In this case, the water below the swinging member 20 will quickly flow out from the water outlet hole 15, while the upper part of the swinging member 20 will continuously be under the action of the water flow pressure. This leads to an imbalance in the water pressure received by the first side wall 25 and the second side wall 26 of the swinging member 20. At the same time, since the lever arm from the first end portion 23 to the swinging axis is smaller than the lever arm from the second end portion 24 to the swinging axis, the direction of the torque of the swinging member 20 will change, prompting the first end portion 23 of the swinging member 20 to swing towards the right side, and at the same time the second end portion 24 to swing towards the left side, that is, causing the swinging member 20 to have a tendency to return to the initial position.

[0081] It should be noted that the first end portion 23 and the second end portion 24 of the swinging member 20 can achieve the purpose of preventing the communication between the water inlet hole 112 and the water outlet hole 15 by approaching the third chamber wall 123 or the fourth chamber wall 124, or can also achieve it by directly abutting against the third chamber wall 123 or the fourth chamber wall 124. This depends on the specific shape setting of the swinging member 20 and the shape setting of the chamber wall of the water passage chamber 12.

[0082] When the swinging member 20 returns to the state of the initial position from the first position, due to inertia, the second end portion 24 of the swinging member 20 will continue to swing towards the left side. At this time, the water flow continues to act on the swinging member 20. After going through the same process as the above process of swinging from the initial position to the first position, the swinging member 20 reaches the second position as shown in Figure 8 At this time.

[0083] After that, the swinging member 20 can repeat the above process under the action of the water flow, realizing reciprocating swinging in the water passage chamber 12 until the water inlet hole 112 stops admitting water, and then the swinging member 20 returns to the initial position again. Correspondingly, the water outlet member can realize reciprocating swinging relative to the main body through the swinging of the swinging member 20. Since the opening axis of the water outlet 461 is perpendicular to the swinging axis, the water outlet device in this embodiment can provide a swinging water spray.

[0084] In addition, referring to Figure 9 , the structure of the above-mentioned second base 16 can be further improved. In Figure 9In the shown water outlet device, only the bottom wall portion of the second base body 16 forms the bottom cavity wall of the water passing cavity 12. The third cavity wall 123 and the fourth cavity wall 124 on the first base body 10 that are used to form the cavity wall of the water passing cavity 12 and are substantially in a vertical position directly extend to the bottom wall position of the second base body 16. At the same time, no corresponding arc segment is provided at the bottom wall of the second base body 16, which makes the cavity walls on both sides of the water outlet 15 not approach each other along the water outlet direction. This structure can facilitate the molding of the second base body 16. At the same time, when the swing member 20 swings, the swing member 20 must swing close to the third cavity wall 123 and the fourth cavity wall 124 that are substantially in a vertical position to ensure blocking the water flow, thereby limiting the maximum swing angle of the swing member 20 and enabling the swing member 20 to have a larger swing amplitude.

[0085] Embodiment 2

[0086] Refer to Figure 10 , Figure 10 shows a water outlet device provided in Embodiment 2 of the present invention. The water outlet device mainly includes a main body, a swing member 20, and a rotating shaft 50.

[0087] The main body includes a first base body 10 and a second base body 16.

[0088] Refer to Figure 10 , on one side surface of the first base body 10, a grooved structure with a special shape is recessed. At the same time, an inlet hole 112 and an outlet hole 15 are respectively formed at both ends of the grooved structure. The hole walls of the outlet hole 15 are away from each other along the water outlet direction.

[0089] The second base body 16 can be covered on the first base body 10 to cover the grooved structure on the first base body 10, thereby cooperatively forming a water passing cavity 12. Among them, the first cavity wall 121, the third cavity wall 123, and the fourth cavity wall 124 of the water passing cavity 12 are formed by the first base body 10, and the second cavity wall 122 of the water passing cavity 12 is formed by the second base body 16. In addition, through holes are respectively provided on the second base body 16 corresponding to the inlet hole 112 and the outlet hole 15. Among them, the through hole corresponding to the outlet hole 15 forms a second base body outlet hole 161. After the second base body 16 is covered on the first base body 10, the second base body outlet hole 161 is located downstream of the outlet hole 15, and its hole walls also move away from each other along the water outlet direction. And the hole wall position at the inlet of the second base body outlet hole 161 is arranged corresponding to the hole wall position at the outlet of the outlet hole 15, so as to make the water outlet smoother.

[0090] The structure of the swing member 20 is similar to that of the swing member 20 in Embodiment 1, except that its shape has changed, and it is swingably connected to the first base body 10 through a rotating shaft 50.

[0091] The rotating shaft 50 is directly fixed on the first base body 10.

[0092] As can be easily seen from the illustrations of Embodiment 1 and Embodiment 2, the swing member 20 can have various shapes. By changing the shape-related attribute features such as the center of gravity position of the swing member 20, the lengths of the force arms at both ends, and the size of the groove, the swing frequency of the swing member 20 can be effectively adjusted.

[0093] Referring to Figure 11 , Figure 12 and Figure 13 , the swing member 20 in the water outlet device provided in Embodiment 2 can achieve reciprocating swing in the same manner as the swing member 20 in Embodiment 1.

[0094] The water outlet device provided in Embodiment 2 can discharge water from the position of the water outlet hole 15 and directly form a swinging water splash. This is because the shape of the water outlet hole 15 is set to a structure in which the hole walls are spaced apart from each other along the water outlet direction, and the water passing area of the water outlet hole 15 is large enough. Taking Figure 12 the state shown as an example, when the swing member 20 swings from the initial position towards the left and its second end 24 leaves the range of the water outlet hole 15, the water on the right side of the swing member 20 will flow out from the water outlet hole 15 along the inclined direction of the swing member 20. Since the water outlet hole 15 has an outward-opening structure, the water flow will not be restricted by the water outlet hole 15, but will flow out of the water outlet hole 15 generally maintaining the direction in which it enters the water outlet hole 15, thereby forming a water discharge swinging to the left; then, during the process of the swing member 20 swinging to the second position as shown in Figure 12 , the water flow on the left side of the swing member 20 will flow out from the water outlet hole 15 along the inclined direction of the swing member 20, thereby forming a water discharge swinging to the right. Through the above method, during the reciprocating swing of the swing member 20, the water outlet device can directly form a swinging water splash.

[0095] Embodiment 3

[0096] Referring to Figure 14 and Figure 15 , it shows a water outlet device provided in this Embodiment 3. This water outlet device can be used for hip washing water discharge in a smart toilet and mainly includes a body, a swing member 20, a rotating shaft 50, an end cap 61, a housing 62, and a fourth sealing ring 63.

[0097] Wherein the body includes a first base 10 and a second base 16.

[0098] The structure of the first base 10 is similar to the structure of the first base 10 in Embodiment 2 and will not be described in detail here.

[0099] The second base body 16 is a cylindrical member, on which there is a slot structure, and a water outlet hole 15 is provided at the bottom of the slot structure. The first base body 10 can be inserted into the slot structure and cooperate with the slot wall of the slot structure to form a water passage cavity 12. At the same time, the second base body 16 is also provided with a corresponding water path, which can communicate with the water inlet hole 112 on the main body to deliver water into the water passage cavity 12.

[0100] The swing member 20 is swingably connected to the first base body 10 through a rotating shaft 50, and its shape is the same as that of the swing member 20 in the first embodiment.

[0101] After the swing member 20 is installed on the second base body 16, the end cap 61 is inserted into the top of the slot of the second base body 16, and a fourth sealing ring 63 is sleeved on its outer wall, which can prevent water leakage during the process of delivering water to the water inlet hole 112.

[0102] The housing 62 is screwed and cooperated with the second base body 16. It can be sleeved outside the second base body 16 and cover the end cap 61, and there is also a water outlet window at the position corresponding to the water outlet hole 15. This water outlet window points to the user's buttocks when the user uses the hip washing function of the toilet.

[0103] Embodiment 4

[0104] Refer to Figure 16 and Figure 17 , which shows a water outlet device provided in this Embodiment 4. It can be used in scenarios such as a shower head. It mainly includes a main body, a swing member 20, a rotating shaft 50, an upper cover 71, a bolt 72 and a fifth sealing ring 73.

[0105] The structure of the first base body 10 is similar to that of the first base body 10 in the second embodiment, and will not be elaborated here.

[0106] The second base body 16 is a cylindrical member, and a plurality of second base body installation bins 162 are arranged around its axis. The bottom of the second base body installation bin 162 is provided with a water outlet hole 15. A plurality of first base bodies 10 can be inserted into the corresponding second base body installation bins 162 and cooperate with the second base body 16 to form a water passage cavity 12.

[0107] The swing member 20 is swingably connected to the first base body 10 through a rotating shaft 50, and its shape is the same as that of the swing member 20 in the first embodiment.

[0108] The upper cover 71 is fixedly connected to the second base body 16 through a bolt 72, and there is a pipeline for water inlet on it.

[0109] The fifth sealing ring 73 is arranged between the upper cover 71 and the second base body 16 to prevent the water flowing into the water passage cavity 12 from the upper cover 71 from leaking.

[0110] In addition, refer toFigure 18 , on the basis of the above embodiments, there is also an Embodiment 5. In this Embodiment 5, an inlet swing member can be further installed on the water outlet device. The inlet swing member is installed upstream of the water inlet hole 112 and is used to alternately input water flow with a certain swing amplitude into the water inlet hole 112. Specifically, the inlet swing member can be integrally formed with the first base body 10, and a water cavity is formed inside it. A swing member water inlet 81 is provided at the top of the water cavity. The swing member water inlet 81 is connected to the external pipeline for water inlet. A cross water outlet 85 is provided at the bottom, and the cross water outlet 85 is communicated with the water inlet hole 112. It should be noted that the water inlet hole 112 should have a large enough size so that the water flow can enter the water passing cavity 12 in a state with a certain variation amplitude.

[0111] A U-shaped wall 82 with an opening facing the swing member water inlet is arranged in the water cavity of the inlet swing member. Two fluid channels are communicated at the two upper end positions of the U-shaped wall 82, namely the first fluid channel 83 and the second fluid channel 84. These two fluid channels are located on both sides of the U-shaped wall 82 and extend along the outer side of the U-shaped wall 82 and cross each other at the position of the cross water outlet 85. The position of the cross water outlet 85 is at the bottom of the U-shaped wall 82. After the water flow enters the water cavity from the swing member water inlet 81, it will impact on the U-shaped wall 82, and then the water flow will randomly reach one of the two fluid channels and then flow into the water inlet hole 112 from the cross water outlet 85, thus forming alternating water output. Since the water output angles of the two fluid channels cross each other, the water flow flowing out from the cross water outlet 85 will show an alternating swing situation, thus forming a water flow with greater disturbance. Such a water flow will better promote the swing of the swing member 20 after impacting on the swing member 20.

[0112] In addition, referring to Figure 19 , on the basis of the above embodiments, there is also an Embodiment 6. In this Embodiment 6, an inlet swing member with another structure can be further installed on the water outlet device. In this embodiment, a water inlet cavity is further provided on the first base body 10. The top of the water inlet cavity is communicated with the external water inlet pipeline for water inlet, and the bottom is communicated with the water inlet hole 112 for sending water to the water passing cavity 12. It should be noted that the water inlet hole 112 should have a large enough size so that the water flow after being disturbed can enter the water passing cavity 12 in a relatively disordered state.

[0113] An inlet swing member is installed in the water inlet cavity. The inlet swing member is mainly composed of a rotating shaft 91 and a swing member 92. The rotating shaft 91 enables the swing member 92 to be rotatably connected in the water inlet cavity. The swing member 92 is a member with a spindle-shaped cross-section in the vertical direction. When the water flow impacts the swing member 92, the swing member 92 will generate oscillations, thereby disturbing the water flow passing through the swing member 92 and making the water flow entering the water inlet hole 112 in a relatively turbulent state. Such a water flow will better promote the oscillation of the swing member 20 after impacting on the swing member 20.

[0114] A swing structure and a corresponding water outlet device provided by the present invention can directly impact the swing member through the water flow, enabling the swing member to achieve reciprocating swing motion, and then cooperate with the water outlet member or agitate the water flow at the water outlet, thereby forming swing water flowers. The overall structure is relatively simple, the reliability is higher than that of the existing water outlet devices with swing water outlet function, and the manufacturing cost is also reduced.

[0115] The descriptions of the above specification and embodiments are used to explain the protection scope of the present invention, but do not constitute a limitation on the protection scope of the present invention. Through the inspiration of the present invention or the above embodiments, those of ordinary skill in the art, combined with common general knowledge, ordinary technical knowledge in the art and / or existing technologies, can obtain modifications, equivalent replacements or other improvements to the embodiments of the present invention or some of its technical features through logical analysis, reasoning or limited experiments, which should all be included in the protection scope of the present invention.
